For example, waste gas discharged from an industrial device usually contains combustible gas, and the content of the combustible gas exceeding the upper explosion limit may cause explosion of the waste gas in the discharging process or the transportation process, so that the regenerative thermal incinerator is required to remove the combustible gas from the waste gas of the industrial device. The raw gas is waste gas which is not processed in the input gas detection device, and the temperature of the raw gas is higher than the working temperature range of the detection module, so that the raw gas needs to be cooled before being input into the detection module.
When the original gas is cooled, the original gas can be input into the condensation module, the temperature of the original gas is reduced through the condensation module, and the gas to be detected with the temperature within the working temperature range of the detection module is obtained.

For example, the material of the heat dissipation pipe in the condensation module and the material of the heat dissipation fin in the condensation module may be a metal material with better heat conductivity, such as copper or aluminum alloy.
Step S604: the conveying module conveys the gas to be detected to the detection module;

Illustratively, the dust filter consists of a filter cartridge, in which case the filtration principle of the filter module is as follows: the raw gas is conveyed to a filter cylinder in the dust filter module, and the tiny air-permeable tissue on the surface of the filter material of the filter cylinder is utilized to block dust with the particle size of more than 10 micrometers (um).
Optionally, the condensation module and the water filtering module may be provided with a water outlet for filtering the original gas with water generated by the condensation module in the process of condensing the original gas and the water filtering module, and/or draining the condensation module and the water filtering module from water separated from the gas to be detected in the process of detecting the gas to be detected.

Mode 1
For example, the on-off valve can be controlled to be opened or closed by using a manual control method, and the on-off valve can be controlled according to the requirement of a user.
Mode 2
For example, the on-off valve may be in communication connection with the drain controller through a serial port, a user writes an instruction into the drain controller according to a requirement, and the drain controller sends a control signal to the on-off valve according to the instruction written into the drain controller by the user to control the on-off valve to be opened or closed.
For example, the drain controller sets the on-off valve to open every second day for one minute. The on-off valve controls the on-off valve according to the setting of the drainage controller.
Step S605: the detection module determines the content of combustible gas in the gas to be detected according to the gas to be detected.
The detection module detects the gas to be detected conveyed to the detection module, and the combustible gas content in the gas to be detected is determined according to the detection result.

Mode 2
Illustratively, a plurality of detectors in the detection module are connected in parallel, and gas to be detected flows through the plurality of detectors for detection when being conveyed to the detection module, so as to obtain a plurality of detection results.
For example, when determining the content of the combustible gas in the gas to be detected according to the detected result, the manner of determining the content of the combustible gas in the gas to be detected may use an average value of the detection results corresponding to the plurality of detectors as the value of the content of the combustible gas in the gas to be detected, or use an average value of the detection results other than the minimum value in the detection results corresponding to the plurality of detectors as the value of the content of the combustible gas in the gas to be detected, or use an average value of the detection results other than the maximum value in the detection results corresponding to the plurality of detectors as the value of the content of the combustible gas in the gas to be detected, or use a median of the detection results corresponding to the plurality of detectors as the value of the content of the combustible gas in the gas to be detected.
For example, the detection gas includes 3 detectors, the detection result of the detector 1 is 30%, the detection result of the detector 2 is 35%, and the detection result of the detector 3 is 37%, where the detection result of the detector 1 is relatively low, the detection result of the detector 2 is accurate, and the detection result of the detector 3 is relatively high, an average value of a plurality of detection results may be used as the content of the combustible gas in the gas to be detected when determining the detection result of the detection module, and in this case, the detection module determines that the content of the combustible gas in the gas to be detected is 34%. The average value of the detection results of the plurality of detectors except the minimum value can be used as the content of the combustible gas in the gas to be detected, and in this case, the detection module determines that the content of the combustible gas in the gas to be detected is 36%. The median in the corresponding detection results of the plurality of detectors can be used as the content of the combustible gas in the gas to be detected, and under the condition, the detection module determines that the content of the combustible gas in the gas to be detected is 35%.
